Just had an Icebreaker for a physics club today, about an hour ago. Basically, we were in smaller groups and that part went fine. I was pretty proud of my fluency for that (haha), but after a few minutes, we introduced ourselves to the entire group. I blocked so hard on my name and, despite being in college and all that, several people laughed. I even announced that I had a speech impediment when I blocked and it didn't really do much. I tried to shrug it off but I died a little afterwards.
